I am using VB .net 2003, I had a working FTP application until the vendor I'm dealing with told me their FTP site is FTPS.. I am trying to integrate your SSL into my code, but I can't get it to work. All the application has to do is sign on to the FTPS, retrieve a file or put a file and logout. If anyone can provide a working example of code on how to do this it would be greatly appreciated. The code can be in c# or VB... I seem to have the code connecting to their server , but I'm stuck on how to issue the FTP commands ie user,pass, get, put... thanks for any help.

You'll have to read the appropriate RFCs and implement them. Here's a start:
